FPGA Based Implementation of Space Vector Modulated Direct Torque Control For Induction Motor Drive

R. Rajendran and N. Devarajan

Abstract—In this paper, a flexible, high computation speed and cost effective field programmable gate array (FPGA) based space vector modulated (SVM) direct torque control for an induction motor is presented. Direct Torque Control (DTC) is known to produce quick and robust response in ac drives. However, during steady state, notable torque, flux and current pulsations occur. They are reflected in speed estimation, speed response, and also in acoustic noise. This paper introduces a new direct torque control (DTC-SVM) for induction motor drive. DTC using space vector modulation is shown to have the low steady state torque ripple, flux ripple and current distortion that is characteristic of space vector modulation and fast transient performance that is characteristics of direct torque control. The above system has been implemented on the Xilinx Spartan 3E FPGA. Simulation and experiment have been performed to prove the feasibility of the proposed strategy.
